Well, I was above to say stern trawler which is used to cash fish with a trawling speed of 4 to 5 knots (seeing the frame at the stern), but then seeing it is a Coast Guard/IN boat, I guess it does tow /dunk some equipment from the stern. Probably some kind of oceanographic /minesweeper / some sonar array towing vessel that drags it in a line behind the vessel.

well it is the INS Sagardhwani. It is used as a research vessel for various fields ranging from acoustic, geological, meteorological, chemical and physical oceanography in the eight labs of the ship and is also used to test torpedoes !!!!

It looks like a research ship, so I looked at Bharat-rakshak.com and this what I think it is: It's Sagardhwani A74 (A research ship). "The vessel has been configured as a research vessel for this Naval Physical and Oceanographic Lavoratory, Kochi". This ship has 8 laboratories "to permit conducting acoustic, geologival, meteorological, chemical and phusical oceanograohy". This ship was "employed in acvance torpedo trials and missile range support". Thanks to BR.com and their contributors for all the information stored on that website.

Indian Navy SAGARDHAWNI - Marine Acoustic Survey & Research Ship. This ship conducts - marine acoustics and chemical oceanography. The role of this ship is significant in mapping sea layers, wave temperatures, fingerprinting enemy and other ships. Also it monitors and works with underwater cables and signals. It supports Deep Underwater marine special forces and deep submersible operations.

This is a fishing trawler of Tri-Services command operated by Indian Navy for catching fish for armed forces canteen. They are readying to set sail hoping to come back by night so that the defence canteens can supply fish curry for the next day's lunch.
